The short, arm

3? of the e in: tlifi hianrlws ttt hrmehw forked s ers are tor I nest is the short ,alrlever of which rlerath'm shown in FW. This tion it will he lewr the front of. which is shown in Fig H. has the long arm 39 Whose lateral faces are in the vertical planes that contain the lateral faces of the short arm 34 of the lever. The branches 38 of the forked levers hirh are on the left of the two central 1e- \tl,- projeet to the left from the parts 36, and the hranehes 38 of the forked levers ieh are on the right of the two central levers project to the right from the parts :1). The branches 38 which extend behind hranehes 37 of other levers are far enough away from the latter branches to enable any lever to do its work without striking another lover. The relation to one another of two adjacent forked levers, when one is in it's normal position and the other in the position which it takes when its upper end rear-her; the limit of its backward movement, are illustrated in Fig. 7. The parts 36 of he forked levers and the arms 39 of the two neutral sub-levers pass through a comb it) which is attaehed to posts 41 that are atlixed to the hast: 1.

Tl .0 key levers of the machine illustrated in 5 and (3, are mounted on a fulcrum rod 13; which fastened at its ends to the posts ll. each of these key levers extending hark ward from the key hoard to the system of sulrlevers and upward to the fulcrum Fu l. On the key levers are rollers 41 which tit and work in the slots in the arms 34 ot' the snhlevors, the pins on Wlilt'll these rollers are mounted having heads 45 which goes the slots :15 and help to keep the rollers in the slots. The key levers pass through a comh 2%) which is fastened to the cross bar 30 ot' the frame, and restoring springs 46, attached to pins formed on a fixed bar i7 and to the key levers tend to keep these levers in their normal positions. It Will he raider-s ood that when the key head of anv ot the kev lovers 42 is depressed the roller ll mounted on the key lever will force upward the arm 3t ot' the snlrlever with lllt'll it is (a'nme ted and the proper type hmwill he operated.

From Fig. 9 and the foregoing descripnnderstood that a system of key levers having hranrhes 26 and 27 and arms Sit and ha ring other siniila arms 20 form-rd on the branches 2th ean he combined with as y tem of Huh-levers having parts 36', lu'anvhes i1? and 38 and arms 15, and havlug); other similar arms-l5 formed on the hranrhes, 3*" ea h key lever having two EHllrl'n mounted on its arms :20 and 20 and tilting in the slots to and 16' in the two short arms of a suhdever. The ln'an l'ies it of the sulrlevers whieh are on the left f the mantral sulrlevers will extend toward he h-l't oi the machine. and the hranehes H of the sub-levers which are on the right of the central sub-levers will extend towardthe right of the machine.

The invent-ion could also be embodied in various other modifications of the structures which are shoyvn herein.

It is evident that key levers having some or all .of the peculiar characteristics of the key levers above described mi ght be embodied in machines not containing sub-levers, such for example as Well known understroke machines, and some forms of visible writing machines, 'and that sub-levers like those above describedmight be used when not combined with key levers. For this reason, and the further reason that these systerns of key levers and sub-levers appear to be novel, they are claimed separately as well as in combination with other levers.
